Rihanna Throws on Her Bikini to Go Tubing in Barbados

Rihanna wore a bikini yesterday for an afternoon on the water in her home country of Barbados. She posed for some silly pictures with her friends while on a boat, then threw on a life vest to go inner tubing. Rihanna's able to let loose with some of her nearest and dearest, but her return to the island was actually for a sad reason. Earlier this week, Rihanna attended the funeral of her grandmother Clara Braithwaite.

The family time came as a break during a busy period of travel for Rihanna. Her various touring and music commitments are the reasons Rihanna's landed on Forbes magazine's richest celebrities under 30 list. Rihanna came in at No. 3 with earnings of $53 million between May 2011 and May 2012. Her payday from her albums was supplemented by her endorsement deals with Nivea and Vita Coco. Only Taylor Swift and Justin Bieber ranked higher.
